In the GMS (Google Mobile Service) usage agreement in the Android 10 version, Google has added a requirement that partners must default to using Android 10's new operating gestures or the traditional Android basic navigation interface in their mobile products.
It's not surprising to have such a requirement. After all, Google long ago required its partners to design Android phones with the three basic operating interfaces of "Home", "Back", and "Menu".
After Android 9.0 began to introduce new operating gestures, Google also recommended that its partners could introduce this design.
However, in the design requirements of various partners, they always add their own operation gestures to meet different functions, resulting in many differentiated gesture operation modes for different Android phones.
Therefore, Google once again requires partners to use the official operation gestures or basic navigation operation interface by default in Android 10. The operation gestures customized by partners can only be enabled through further settings, and they cannot even actively recommend users to switch to other operation methods.
